“Whats weird is that when my wife tries to email me from her gmail account to myemail@mydomain.com, sometime it goes through and sometime it doesn’t. But when I send email from my gmail account to myemail@mydomain.com, it always goes through.

Could gmail’s mail server IP be partially block and my wife’s account just so happened to be in the blocked gmail’s mail server IP?

No big deal.. just sharing my observation.”

A:

“I am sure Gmail has gazillion of IP addresses and they will always rotate their IP for their outbound email.

I noticed the same thing as well. One day I am NOT able to send from my gmail, and the next its fixed.”
